How This Calculator Works
Fraction arithmetic uses common denominators for add/subtract and direct multiplication for ×/÷. The result is simplified by dividing both terms by their greatest common divisor.
Formula
a/b ± c/d = (a·d ± c·b)/(b·d); multiply numerators & denominators
Example
3/4 + 2/3 = 17/12 (or 1 5/12), which equals 1.4167.
